Table 11. Status Register Bits
Read Electronic Signature
The device contains a Manufacturer Code and De-
vice Code. To read these codes two steps are re-
quired:
1.
first use one Bus Write cycle to issue the Read
Electronic Signature command (90h), followed
by an address input of 00h.
2.
then perform two Bus Read operations – the
first will read the Manufacturer Code and the
second, the Device Code. Further Bus Read
operations will be ignored.
